When someone tries to open WhatsApp it displays a dialog box to enter PIN and will only pass if the combination is correct. By default, after you install the app, WhatsApp is immediately locked when you leave but you can change the behavior so that it gets stuck after a certain interval of time that can be set between 1 and 15 minutes.
If someone tries to access WhatsApp and inserts an incorrect PIN, it will take a picture of the offender and save on your phone! Of course this only works if your smartphone or tablet features a front-facing camera. WhatsApp Lock: Keep Privacy is free (with banner) and available in the Google Play Store and is compatible with Android 2.2 and higher.
